fix: support setting iOS pip window sizes

[santhoshvai]

💡 Overview

iOS pip window did not know what size to set. And so size was set by the OS. This was not ideal as it seemed to completely random at times. In this PR we add support for PiP window size based on track size.

Sends track dimensions from JS to Native

[Copilot]

Pull Request Overview

This PR implements support for setting iOS Picture-in-Picture (PiP) window sizes based on video track dimensions. Previously, the iOS PiP window size was determined by the OS, leading to inconsistent sizing. The solution tracks video dimensions from JavaScript and passes them to the native iOS layer to set appropriate PiP window sizes.

Key changes:

• Updates to @stream-io/react-native-webrtc dependency from 125.4.0 to 125.4.1 across all packages
• Enhanced useTrackDimensions hook to better track video dimensions
• New native iOS methods to handle PiP content size updates with caching mechanism
